Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

Inhibiting eukaryotic initiation factor 5A (eIF5A) hypusination attenuated activation of the SIK2 (salt-inducible kinase 2)-p4E-BP1 pathway involved in ovarian cancer cell proliferation and migration.

Lee GK, Kim HY, Park JH

Eukaryotic initiation factor 5A hypusine (eIF5AHyp) stimulates the translation of proline repeat motifs. Salt inducible kinase 2 (SIK2) containing a proline repeat motif is overexpressed in ovarian cancers, in which it promotes cell proliferation, migration, and invasion.Western blotting and dual luciferase analyses showed that depletion of eIF5AHyp by GC7 or eIF5A-targeting siRNA downregulated SIK2 level and decreased luciferase activity in ...
